FAC [factory setting] 
 

FLD 

—This parameter is used to specify 

which set of calibration values you want to use. 

—Uses built-in calibration values (stored in read-only 

memory). 

—Uses calibration values stored as a result of the field 

calibration procedure described in Section 5. 

 Until field calibration has been done,  

FLD uses the same calibration values as FAC. When field 
calibration is performed, the value of LD CAL is automatically set to 
FLD at the completion of the field calibration operation.

 in engineering units is displayed but 

can only be configured for linear input type.  

Otherwise, this is a read-only display of the higher range value for 
the selected T/C or RTD input type.  

•  Scale the input signal to the display value you want for 100 %. 

•  EXAMPLE: 
  Actuation (Input) = 4 to 20 mA 
  Process Variable = Flow 
  Range of Flow = 0 to 250 Gal/Min 
  High Range display value = 250 
  Then 20 mA = 250 Gal/Min

−

 

 in engineering units is displayed but 

can only be configured for linear input type. 

•  Otherwise, this is a read-only display of the low range value for 

the selected T/C or RTD input type. 

•  Scale the input signal to the display value you want for 0 %. See 

example in “INPHI”. 

–99.9 to 999.9 
 
 [factory setting = 0] 

—Used to compensate the input for drift of an input 

value due to deterioration of a sensor, or some other cause; select 
the value you want on the input. 

0 to 120 seconds 
No filter = 0 
 
[factory setting = 0]

 

—A software digital filter is provided for the 

input to smooth the input signal. You can configure the first order 
lag time constant from 1 to 120 seconds. If you do not want filtering, 
enter 0.
